Property Management - Refrigerant ConversionThe most simplistic and least costly option to maintaining and existing piece of R-22 equipment is to convert the system to a direct replacement refrigerant. ICOR International’s NU-22B® (R-422B) is a non-ozone depleting, non-toxic, and non-flammable direct replacement that nearly duplicates the operating characteristics of R-22. System conversions to NU-22B do not require the use of any product specific materials or components. Therefore property managers can extend the lifespan of both the indoor and outdoor units and avoid any costs associated with flushing or replacing system piping. For the property management industry, NU-22B is the safest, most simplistic, and by far, the most affordable option for maintaining existing R-22 designed equipment.
